Reviewer notes

Use this space to describe your geocache location, container, and how it's hidden to your reviewer. If you've made changes, tell the reviewer what changes you made. The more they know, the easier it is for them to publish your geocache. This note will not be visible to the public when your geocache is published.

Are you of sound mind? And have you studied enough to be able to read and write?

Have you always yearned to rub yourself in the dust even though you have yet to find a good excuse for it?

Do you have friends with equal (or greater) degrees of insanity?

YES? Than you have been chosen!

Take your GPS receiver, a torch and helmet and put on any clothes that you don’t mind getting absolutely filthy and join a few of your friends for a cache hunt!
What you are looking for sits underneath a small pile of rocks as shown in the image which itself sits on a much larger pile of rocks, approximately 1.80m above the floor level. Please leave everything as you found it!
To get there you will have to snake your way across a dusty floor and through a narrow passageway. Although this passageway is narrow it will allow safe passage for the largest geocachers that I know... ;-)

Although I cannot yet be absolutely certain the development of the mine seems to follow the same rock strata.

Basically, the mine has been developed in marly limestones that overlie a series of crystalline limestones. The underground development seems to be a necessity in order to follow ever deepening strata of crystalline limestones.

In one of the galeries you can still observe a cut block of these crystalline limestones with an edge that shows signs of having been worked on. Not too far from this block is a section of these crystalline limestones with the marly limestones removed.

The crystalline limestone was probably used for the manufacture of door and window frames.

The presence of the mines is enigmatic up to a point because these rocks are not that good a quality but the mines exist nonetheless...
